Earth Observation (EO) Space Missions provide global coverage of the Earth by generating on a continuous basis huge amounts of data from a variety of sensors. Locating and accessing these historical data is a difficult process and their interpretation can be even more complicated given the fact that scientists may not have (or may not have access to) the right knowledge to interpret these data....

In this paper, we establish a new analogue of the classical Bonferroni inequalities and their improvements by Galambos for sums of type ∑ π∈P(U)(−1)(|π| − 1)!f(π) where U is a finite set, P(U) is the partition lattice of U and f : P(U) → R is some suitable non-negative function. Applications of this new analogue are given to counting connected k-uniform hypergraphs, network reliability, and cum...

A vital constituent of a virus is its protein shell, called the viral capsid, that encapsulates and hence protects the viral genome. The surface structures of a large number of icosahedral viruses can be modelled via Caspar-Klug Theory, which has hence become one of the fundamental concepts in virology. However, growing experimental evidence have shown that a significant fraction of viruses fal...

Purpose – The purpose of this paper is to describe the use of XML formatted data unit (XFDU) technology to implement OAIS-based information packaging in the CASPAR project. Design/methodology/approach – The paper outlines new tools and techniques in working with XFDU for the purpose of preserving complex digital information. Findings – The preservation of digital assets was facilitated by using...

The anterior cervical plate fixation systems have been widely used in treatment of complex spinal disorders such as traumatic lesion, disc hernination, tumor, spondylosis, arthritides, and others. Combined with bone graft or other fusion techniques the satisfactory outcomes were higher than 88% (Clements 1990, Naito 1993,Bose 1998, Schneeberger 1999). Among the screw plate fixation systems, Cas...

2 Research Geologist, USDA Forest Service Pacific Southwest Research Station, Redwood Sciences Laboratory, 1700 Bayview Dr., Arcata, CA 95521 Abstract: Cumulative effects are the combined effects of multiple activities, and watershed effects are those which involve processes of water transport. Almost all impacts are influenced by multiple activities, so almost all impacts must be evaluated as ...
